My wiring is also a mess, and I was turned down by Ford about a year ago because I was over their 100K limit (was 105K, now 121K). It sounds as if there might still be some hope in getting Ford to at least help with the costs. I even offered to install it myself (right now I have the intakes off (Duratec) and the wiring going to the injectors is a disaster), but Ford wanted over $900 for the harness!

If anyone has a better angle on how to approach this with Ford, I'd love to hear it! Thanks!
